VALVE FOR FILLING BOTTLES.

Application med December 2, 1915.

To all whom it may concern.'

Be it known that I, CHARLES S. ADAMS, a citizen of the United States, residing in the city of Buffalo, county of Erie, and State of New York, have invented certain new and useful Improvements in Valves for Filling Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable ethers skilled in the art to which it appertains to make and use the same.

This invention is directed to the provision of an improved form of valve for use in filling bottles with a liquid from a suitable receptacle. The invention is of special utility in valves for use in filling milk bottles, a plurality of the valves being located 1n the bottom of a receptacle Jfor the milk in positions to .coact with the open necks of a plurality of bottles supported in a suitable crate which is' raised vertically to carry the necks of the bottles into engagement with the valves.`

Valves for this use have heretofore been commonly constructed consisting of two telescoping tubular members and a spring coiled about them to hold them normall extended, the lower end of the lower tubu ar member bein adapted to be engaged by the neck of a mi k bottle and raise thereby against the tension of the spring. In combination with these parts, an air tube is employed extendin throu h the tubular members and prov1ded wit an enlargement at its lower end which coacts with the vlower end of the lower tubular member to open and close the pasr sage for the flow of the milk into a bottle. In valves of this character, various means have heretofore been devised for supporting the air tube. This tube should not e supported rigidly as sometimes its lower end 1s engaged by the neck o f a bottle and the tube should therefore have a slight capacity for upward movement to guard against breaking the neck of the bottle. Also, the air tube should be supported in such a way that its support, or a portion thereof, may be readil withdrawn to permit the tube to be passedy downwardly through the telescopin' tubular members, as in this way the parts of the valve may be quickly detached one from another for cleaning.

With these ends in view, it has been 1proposed heretofore tomount a supportin device detachably upon the upper end o the Specication of Letters Patent.

serial No. 64,625.

tubular members arranged to coact with a shoulder on the air tube to support the latter and provided with a side o ening whereby it may be moved laterally with respect to the air tube and thus become detached from the latter. Such a detachable support for the air tube I have found to be open to very serous objection in that it may, and in use frequently does, become unseated, thus requiring either that the milk be drawn oli' from the reservoir to permit of reseating the support or that the operator reach into the milk and lposition the support. It will be understoo that when the crate of bottles is raised mechanically into coaction with the lower ends of the valves and the valves operated to open them, the parts of the valves are subjected to a severe jar which is frequently suflicient to cause the unseating of a relatively light supporting member not securely fastened in position.

I have found that this objectionable characteristic of such valves as heretofore made may be avoided, and for this purpose have devised an improved construction wherein the parts are so constructed and arranged as to eliminate all danger of disarrangement of the parts during the operation of the apparatus. The improvement consists primarily in forming the major portion of the support, that is, the portion provided with an opening through which the milk fiows from the reservoir into the valve, integral with one of the tubular members of the valve. This portion of the support for the air tube has a ring at its upper end rovided with a central opening of a size su cient to permit the upper portion of the air tube to pass therewith an enlar ement 14 including a washer 15 which is a apted to coact with the lower end of the tubular member 6 to close and open the passage through the latter. The air tube has a central passage therethrough opening upon the sides of the conical enlargement 14 and its function isto permit the escape of air from a bottle up'- wardly through the air tube as the milk flows downwardly through the member 6 into the bottle.

The air tube 13 is so supported, as to permit it to be moved upwardly b a bottleV if the neck of the bottle engages t e lower end of the tube. Also, it is so supported as` to permit of its detachment yfrom the supporting means in which case the air tube may ico los

viio

be lowered through the tubular members 5 I(und (j and disengaged therefrom, whereupon the paints 5, (i z nd l :nay be disengaged. In this way, ull o the parts of the vulve muy be quickly detached 'For cleaning.

The means for supporting the air tube 13 consists of parts extending ulnvul'iily from the tubular n'lember 5 and, formed integral therewith, and n detaehuble supporting de vice seated upon these parts. 1n the drawin s, it will be seen that the` tubulin' ineinbe 5 which is' ads 4"sedi lt'o be selfiurerl toL t 1e bottom `of thel'revseri oir is extended iili'ivailly by'strhtsor 'Stendal-ills 16` which :ire tfornreil egrul with the tubular niiunh'ei" 5l. i', upper Iemi of thesehtrnts or stunilarils ,it is .fi ring 17? nlsoforn'udes au intgral par( of thetubiihtr ineml'iei lt will l'ienolml, 'particularly froml Fig. 1, that below lliis ring,l` l' openings are provided between the sti-ntf: 1,6 leading to the interior ofl the tubular nwni bei 5, ndit is through these opiiijiings that the milk passes from the reserro'ir into the vulve.
